4.7 Exposure Techniques
As an intra-oral dental X-ray system, the KaVo
NOMAD PRO 2 can be easily positioned. This high
degree of flexibility makes it easy to take exposures
while the patient is reclined, lying completely on their
back, or sitting upright. Ensure the patient is protected
by using an apron.
When taking images, operators may hold the
KaVo NOMAD PRO 2 by having both hands on the
handset grip, or, for increased stability and patient
safety, by placing one on the grip and the other
on the underside of the housing (but not on the
collimator cone).
Position the KaVo NOMAD PRO 2 relative to the
imaging system to minimize cone-cutting. (If your
practice uses film holding kits or aiming devices,
check compatibility in advance.)
Exposure times increase proportionally when the
imaging angles vary away from 90° (or perpendicular)
to the film or sensor. To maintain low patient X-ray
doses and to keep the operator within the protection
zone, have the head of the patient slightly tilted, and/
or raise or lower the chin as needed. (See
Section 2.1
Radiation Safety.
)
When the device must be angled and the
operator cannot be completely within the protection
zone, ensure operator protection through the use of
proper safety measures, such as the use of an apron.
(See
Section 2.1 Radiation Safety.
)
Avoid touching the patient with the cone or
backscatter shield; disposable plastic coverings can be
used to prevent cross-contamination.
Determine what KaVo NOMAD PRO 2 exposure
time settings deliver optimal results for the type of
imaging (digital or film-based) that is used on a
regular basis.
NOTE:
Both digital imaging sensors and film and phosphor plate speeds can vary
somewhat in their characteristics and could require different exposure settings to meet
density preference. (See
Section 4.10 Settings Menu
for more information.)
